Accessed 2 Februar 2013. The Actinopterygii is the class of ray-finned fishes . Members of this superorder are sometimes called ray-finned fishes for the characteristic sharp, bony rays in their fins; however this name is often given to the class Actinopterygii as a whole.

They are so called because of their lightly built fins made of webbings of skin supported by radially extended thin bony spines … See more Actinopterygii: ray-finned fishes. The ray-finned fishes get their name from the fact their fins are webs of skin held by bony or horny spines ("rays").0. The gills are usually found in one or more slits in the skin behind their heads. The fins are composed of a membranous web of skin supported by a varying number of spines and soft rays.g., the l ungfish and coelacanth), which have fleshy fins. 2012; Lu et al.

This is different from the fleshy fins of the fish in the Sarcopterygii. The name means "ray-finned," for unlike the Chondrichthyes, the fins of the Actinopterygii are webs of skin supported by bony or Learn about the anatomy, evolution, and diversity of Actinopterygii, the most diverse group of Chordata with about 33,500 species of ray-finned fishes.3. The most ancient fossils known of the group are scales from the Late Silurian. 118 ). The Actinopterygii may be the largest, most varied and presumably most intensively-studied vertebrate group, but there remains much debate about the timing and extent of early evolutionary development. Ray-finned fish first appeared in the Silurian period . While everyone knows that fish live in water and breathe through gills, the simile "like a fish out of water" does not always apply to ray-finned fish. The ray-finned fishes get their name from the fact their fins are webs of skin held by bony or horny spines ("rays").Understanding their phylogenetic relationships allows us to consider the evolutionary processes responsible for generating such diversity. Actinopterygians comprise three evolutionary radiations: Chondrostei, holostean, and Teleostei. Existing phylogenies suggest this WoRMS (2024). They can be found in both fresh water and marine environments from the deep sea to the … skeletons of true bone(sturgeons and paddlefishes are exceptions). This separates them from the lobe-finned fishes (Class Sarcopterygii, e. They have fleshy tentacles above their eyes and below their mouth, and long, fanlike pectoral fin. Acanthopterygii (meaning "spiny finned one") is a superorder of bony fishes in the class Actinopterygii. The ray-finned fishes are so-called because their fins are webs of skin supported by bony or horny spines (rays), as opposed to the fleshy, lobed fins that Classification of the tremendous diversity of ray-finned fishes (Actinopterygii) began with the designation of taxonomic groups based on morphological similarity. Albuliformes: pictures (1) The Actinopterygii are divided into two classes: Cladistia (bichirs), represented by a single modern order (Polypteriformes) restricted to Africa, and Actinopteri, with the subclasses Chondrostei and Neopterygii. Datando do período Permiano, os Actinopteri compreendem os Chondrostei e os Neopterygii. The inference of organismal phylogeny is now based on many independent genetic loci, a widely accepted approach to assemble the tree of life. They are found in every aquatic habitat from the abyssal depths of the ocean to freshwater Ray-finned fishes constitute a major source of food for millions of people.

A gill cover is used to pump water through the gills, enabling the bony fish to Osteichthyes, known as the bony fish, are a taxonomic class (or superclass) of fish and the largest class of vertebrates in existence today.They can be contrasted with the Osteichthyes or bony fish, which have skeletons primarily composed of bone tissue. This find is important given the paucity of Spathian osteichthyan sites. Almost all fish that you see belong to this class of fish. Dating back to the Permian period, the Actinopteri comprise the Chondrostei ( sturgeons and paddlefish ), the Holostei ( bowfins and gars ), and the teleosts. skeletons of true bone(sturgeons and paddlefishes are exceptions). Here's a graph of the models release schedule since early 2022 (segments extend from data export date to model release date) and how the number of species included in each model has increased over time.

In fish: Actinopterygii: ray-finned fishes. They have sexual reproduction. Introduction. Actinopterygii differ from the other group of Teleostomi fishes, the Crossopterygii, by the absence of the central axis of basal elements of the skeleton in the paired fins.
